IMO...
The origional Chevy (also Pontiac and maybe Olds) tri-power used Rochester carbs. Rochester had 2 designations....similar to Carter....1 1/4" and 11/2" designs. The big 2bbl, was rated at 435 CFM where the smaller carb were used on small block engines, 283, 337, 350, etc. The origional tri-power were vacuum operated and later became mechanical with accelerator pumps on the end carbs. Since the original Mopar 6 barrel used modified Holley, SIMILAR to the. carbs as used on the 400 hp and 435 hp Corvette 427 engines, something from those engines may be what you seek....but...the fuel lines and throttle linkage will have to be fabricated. Since those carbs have different mounting dimensions, it is unlikely that a Mopar air cleaner assembly would fit.
If you want to get a six barrel (or six pack) setup, why not just buy a Mopar set up rather than shoe maker a Rochester system?? The Mopar set up is available from several sources on line. BTW....vacuum secondary operation is superior. But you could adapt a Ford tri-power similar to that used on the old 401 hp/390 or the 405 hp/406 engine or the 425 hp/427 engine, both are mechanical operation.....then you would have something really unusual....the carbs are mounted backward, with the fuel bowls mounted facing rearward. Just my opinion of course.
